LED T15/W16W bulbs (921) – wedge base bulb for reversing lights. T15 is similar to T10/W5W but is slightly larger and has higher power. T15 is used almost exclusively as a reversing light bulb in modern cars. Switch to LED for brighter, whiter reversing lights that make reversing safer in the dark.

The T15 (W16W/921) has become the standard reversing light bulb in most modern cars. It sits in a wedge socket similar to the T10 but is wider and has thicker contact pins for higher current draw. The LED replacement provides significantly brighter reversing lights – a common upgrade that makes a big difference when reversing in the dark and at dusk.
T15 and T10 look the same but have different socket widths. T15 is wider and will not fit in T10 sockets. Always check which socket your car has. If your car has T10 as a reversing light and you put in a T15, or vice versa, it will not physically fit.
